Specification of Letters Patent.

Patented March 13,1906;

To all whom it may concern: Be it known that I, ULYssns GRANT Rus- SELL, a citizen of the United States, residing at Marysville, in the county of Marshall and 1 My invention relates to window-ventila tors; and its'object is to provide such a structure which is particularly simdple, durable, and eflicient and which is-inten edto occupy the space in an openwindow, as the space below a raised sash, and 18 so constructed as to.

admit of a maximum vpassa e or circulation of air when the parts thereo are in one position and efiectually exclude the entrance through the window of rain, snow, or the like when the parts are in a second position, while admitting of -a more restricted passage or circulation of air.

The invention comprises the combination and arran ement of component parts to be hereina ter described, and particularlyv pointed out in the claims.

The invention is susceptible of various embodiments, and the accompanying drawings 7 illustrate, andI' shall hereinafter describe in connection therewith, what is now conceived 'to be a preferable exemplification of the same.

In the drawin s, Figure l is a front elevation of the venti ator. Fig. 2 is a plan view of the same; and Fig.3 is a cross-sectional -view on the line- 1 1, Fi

.1., 1 The invention inclm ies generally a main frame-and sections movably mounted therein, each including a plurality of slats, which are moved bodily when the section of which they constitute a part is shifted inthe mainframe.

In the illustrated exemplification of the invention the main frame is of rectangular shape, so as to fit within theflordinary window-casing in the space provided by raising thelower window-sash and is illustrated as formed of two parts orsections -1 2,.suitably hinged together, as at 3. The movablev sec tions are mounted within the openings in the parts 1 2 and are so constructed that in one position thereof the passage of rain, snow, or

v the like throughthe window-opening will be 'efiectually prevented and a restricted space provided at the same time for aircirculation, while in a second position of the sections a ordinary sash is greatly facilitated.

Application filed December 20,1904. Serial No. 237,719.

provided for the circulation of air.

V In the exemplification of "my invention shown in the accompanying drawings each movable section includes a plurality of slats 4, which are held at their ends in end plates orvbars 5. The plates or bars 5 are intended -to fit snu ly within the openings in the main frameian are provided with pintles or studs 6, finding bearings in the walls of the opening in the main frame and upon whichthe movable sections are intended to be turned.

The movable sections. are preferably ar ranged in pairs, and the members of each pair have complemental obliquely-disposed ends, which abut againsteach other when the sections'occupy their vertical positions. The slats 4 of each section are preferably equidistantly spaced and disposed in an oblique position'in a similar manner to the slats of the ordinary shutter, so as to effectually exclude 4 relatively large unobstructed space will be rain, snow, or the like, while admitting of a restricted passage of air when the sections occupytheir vertical positions. If a greater circulation of airis desired through the windowo' ening, one or both of the sections are inten ed to be turned into. a'substantially horizontal position, as shown in Fig. 3.

For the purpose. of retaining the movable sections locked in their vertical positions a suitable lockingplate 7 is preferably associated witheach pair of said'sections, said plate extending across the adjacent ends of the members of each pair upon the inner faces of the same and being movablysecured to one of the sections, as by a pivotal connection." By reason of the sectional construction of the main frame the insertion and re-' moval of the same into the guideway for the The construction and operation of 'my' invention will be readily understood upon reference to the foregoing description and accompanying'drawings, and it will be appreciated that the'pa-rts and combinations recited may be varied within a wide range without departing from the spirit and scope thereof. I i

Having thusdescribed the invention, what is claimed as new, and desired to be secured by Letters Patent, is- Y 1. As an article of manufacture, a windowventilator, comprising a main frame having two openings arranged side by side thereln, a

pair of coacting sections mounted in each ICC iro

opening, said sections including end plates and cross-slats rigidly mounted in the plates, and pintles projectin from said plates substantially centrally 0% the same, and finding bearings in the side walls of the main frame.

2. As an article of manufacture, a window- Ventilator comprising a main frame having two openings arranged side by side therein, a pair of coacting sections mounted in each opening, said sections including end plates and cross-slats equidistantly spaced and rigidly mounted in the end plates, the slat at the end of each section coacting with the adjacent section being so spaced that the distance between the adjacent slats of the two 15 sections will be substantially the same width, when the sections are in closed position, as the distance between the remaining slats of each section, whereby when the sections are closed the same present a unitary or uniform 2o appearance.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ULYSSES GRANT RUSSELL.
